Abstract:
Physiological and/or behavioral characteristics of
humans such as face, gait and/or voice have been used in biometric
recognition technology. Apart from those characteristics
reported in the literature, the hypothesis of this research was
to initially investigate if human facial behaviors could also be
used as another behavioral traits for human identification. We
used kernel subspace analysis method to analyze the data so
as to support our hypothesis. We used the Japanese Female
Facial Expression (JAFFE) database as it provides the facial
behavior traits for data collection. The experimental results
indicate that facial behaviors may provide information about
individual differences, thus may be used as another behavioral
biometric.
